VACUUM SUCTION Device.

Specification of Letters latent.

Patented Apr. 3, 191?.

Application filed August 15, 1916. Serial No. 114,941.

To all whom it may concern:

Be it known that 1, JOHN SORENsEN, a citizen of the United States, andresident of Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Vacuum Suction Devices,of which the following is a specification.

The object of my invention is to provide a generally improved vacuumsuction device adapted to be operated by one hand and of such a sizethat it may be easily carried about and used as a first aid instrumentin cases of poisonous snake or insect bites or similar cases, the ideabeing that when a person is bit by a snake or insect, the applicationand operation of my suction device serves to draw out or suck out thepoison in the wound and prevent it from spreading. Obviously such adevice is of great utility for soldiers and travelers in the tropicalzones.

With the above and other objects in view myinvention is embodied in avacuum suction device constructed as hereinafter described and asillustrated in the accompanying drawing in which Figure 1 is aperspective view of a device embodying my invention and illustrating theuse thereof.

Fig. 2 is a plan view of the device, and Figs. 3 and 1 are views inelevation at right angles to each other.

In the drawing the reference numeral 5 denotes a pump cylinder or cuppreferably made'of glass. The lower end or mouth 6 is open, while theupper end is closed by a cap 7 provided with a top plate 8 which isextendedas shown to afford a finger rest 9. 10 is a piston of anysuitable construction adapted to move substantially airtight within thecylinder 5 by operation-of the piston rod 11. The latter is actuated bymeans of the crosshead 12 which is secured to the piston rod by a nut13. The crosshead is formed with two diametrically opposed guide rods14, 14 which form handles 15, 15. The guide rods 14 slide in notches 16,16 in the top plate 8.

In operation the thumb of the operator is placed upon the finger rest 9and the first 1 and second fingers grip beneath the handles as shown inFig. 1. The mouth 6 is placed over the wound or spot where the suctionis to be applied and by a simple closing of the fingers, the piston isdrawn up into the cylinderand the poisonous matter sucked or pumped intothe latter and may thereafter be removed as will be understood. Theoperation may thereafter be repeated until the wound. is in conditionfor dressing or other application.

Similarly the device may of course be 'used for massaging purposes.

It will be noted that the device is quite small and easily operated byeither hand to be applied to nearly all parts of the'body. The guidingrods 14 are made quite stiff and their moving in the notches 16 insuresan even steady pull upon the piston.

While I have illustrated my invention as embodied in a preferred form, Ido not thereby intend to be limited to the exact details shown, butclaim such changes and modifications as are within the scope of theappended claim.

I claim A vacuum suction device comprising a pump cylinder, a pistonmovable therein, a cap and top plate for closing the upper end of thecylinder, a piston rod secured to the piston and projecting through saidtop plate, a cross head secured to the piston rod, oppo sitely disposedguide rods integral with said cross head and forming operating handlesand means in said top plate for guiding the said guide rods.

Signed at New York in the county of New York and State of New York this11th day of August, A. D. 1916.
